powerpc/eeh: I/O chip EEH enable option The patch adds the backend to enable or disable EEH functionality for the specified PE. The backend is also used to enable MMIO or DMA path for the problematic PE. It's notable that all PEs on PowerNV platform support EEH functionality by default, and we disallow to disable EEH for the specific PE.
